As part of the extended deterrence talks in recent years, Tokyo and Washington have held multiple tabletop exercises to strategize a scenario in which a conflict broke out in East Asia and the United States is pressured to use nuclear weapons, according to the sources.

With that in mind, Japan and the United States reviewed how to coordinate and how to deal with issues stemming from the possible use of nuclear weapons, such as managing public opinion. Discussions also broached how much information the United States can share with Japan, the sources said.

A totally normal thing to do and publicly report I'm sure.
